DSTH01 is a type of digital relative humidity and temperature sensor module which integrates temperature and humidity sensor elements, an analog-to-digital converter, signal processing, calibration data and an I2C host interface. Both the temperature and humidity sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory which ensures the DSTH01 modules are fully interchangeable and no recalibration or software changes are required. Necessary components are integrated on the DSTH01 modules so users can get a quick start with the microcontroller with extra design. The sensor top is covered with silicon gel which can protect the sensor from the dust and other particles. The module works at 2.1~3.6V. It consumes about 240uA during RH conversion and 1.5mA in normal work mode. The DSTH01 module offers an accurate and factory-calibrated solution for embedded applications ranging from HVAC/R system to consumer electronic products.
